Client is Horrible

I have been unable to view stats and basically my entire profile and shop. I tried to access them prior to accepting a match. When I accepted the match the screen went black and I had to dodge as I could not pick a champion. I shouldn't be losing lp to a client issue that I have no control over. I constantly have to restart the client as it is so buggy and I am unable to view anything. This is getting ridiculous, the old client was better.
